Double Drum Hoist Winch direct measurement principle:
According to different measurement methods, the depth indicator can be divided into direct type and indirect type.
In principle, the following methods can be used for direct measurements:
① magnetic strip on the wire rope;
② Use ordinary wire rope flowers as travel signals;
③ Use high frequency radar, laser or infrared ranging equipment.
The advantage of this depth indicator is that the measurement is direct, accurate and reliable, and it is not affected by wire rope slippage or creep.
In indirect measurement, the position of the lifting container in the wellbore is measured indirectly through the transmission mechanism connected to the lifting container. Usually, the measurement is made by measuring the rotation angle of the drum of the Double Drum Hoist Winch and then converting it into a stroke. The advantage of this depth indicator is that the technical equipment is simple and easy to implement. The disadvantage is that the volume is large, the indication accuracy is not high, and it is easily affected by factors such as wire rope slippage, creep or tensile deformation.
Double Drum Hoist Winch is mainly composed of spindle device, rope adjusting mechanism, disc brake device, hydraulic station, depth indicator, reducer, speed generator device, elastic coupling, gear coupling, motor, operating table and electrical Control system and other components.
多少 How many Double Drum Hoist Winch settings do you need to know?
1. Double Drum Hoist Winch should be placed on a high and flat place;
2. There should be a sleeper under the base, and the sleeper must not protrude from the base at one end of the foot brake.
3. The operation position of Double Drum Hoist Winch should have good vision;
4. The wire rope should be drawn in from under the drum;
5. The wire rope on the drum should be neatly arranged;
6. The wire rope on the Double Drum Hoist Winch drum should be kept at least 5 turns during work. The outer rope should be no more than the rope diameter at the edge of the drum. Direct and indirect.
